MT7810 is a high precision LED constant current control chip operating at critical conduction mode (CRM) with zero current switched-on and peak current switched-off. It’s mainly targeted for non-isolated buck LED power systems.

Critical conduction mode ensures that the MT7810 turns on the power MOSFET when the inductor current reaches zero, reducing the power MOSFET switching loss, the system achieves more than 95% efficiency. With critical conduction mode, and the line compensation, MT7810 outputs high accuracy LED current, and further achieves good line regulation and load regulation.

MT7810 has wide working voltage range, which is suitable for full-range AC input or 10V-400V DC input voltage. MT7810 provides various kinds of protections, such as over current protection(OCP), short circuit protection (SCP),over voltage protection (OVP) and over temperature protection(OTP),etc, to ensure system reliability.
